LCD graphics units are intelligent graphics displays with an RS-232 serial interface.
With two or three integrated character sets and a wide range of graphics functions, they permit the use of the latest LCD graphics displays, thus saving time and costs.
Apart from a supply voltage of +5V and RS-232 data, no further signals are required. No additional software or drivers are required for their operation.
All the graphics routines are integrated in the display's in-built high-level graphics controller. This permits the creation of a clear and attractive display using only a few commands.
